BULB DESIGN

HP48: This bulb is non-polar, CK compatible, with 48 Epistar 3014 LED chips. Thanks to the cap on the top, the light from this High Power Bulb is shined backwards and away from the bulb, not straight out. This means the output is excellent, because it uses the vehicle's housing completely, which then shines the light much more uniformly.

HP11: Four side-firing 1.5W-rated Osram LED chips, and one 5W-rated LED chip on top, which is projected by a lens for maximum effective brightness. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.

XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.

Fitment. All three bulbs use a quality inject-molded 3156 terminal, with a locking base connector and proper pin alignment, designed for exact replacement of your factory 3156 bulb.

BRIGHTNESS

Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb:

HP48: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern instant on/off of LED technology.HP11: Slightly higher brightness than OEM bulbs.XP80: Much brighter than OEM bulbs. These are bright!

Lumens.BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.

These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.

QUALITY

LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.

While Diode Dynamics bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the Warranty Information page.

Backup LEDs are a direct replacement. Just change the bulb! You will not need any resistors or other accessories.

Remove your factory bulb

1. Access your backup bulb. You may need to pull back the trunk/cargo carpet and/or unscrew the visible nuts holding the light in.

2. Remove the socket from the tail light by twisting counterclockwise.

3. Remove the factory bulb by unclipping and pulling it out of the socket.

Install your new LED bulb

1. Plug new LED bulb into socket by pushing it into place.

2. Test the bulb to ensure proper function.

3. Insert socket back into tail light, and reassemble as necessary. That's it!
